FRANKLIN \V. KELLY, OF VERMONTVILLE, MICHIGAN.

SHUTTER-WORKER.

QPECIPICATION forming part of Letters Patent No. 391,898, dated October 30, 1888.

(N0 model.)

To aZZ whom, it may concern.-

Be it known that I, FRANKLIN \V. KELLY, of Vermontville, in'the county of Eaton and State of Michigan, have invented a new and useful Improvement in Shutter-W'orkers, of which the following is a full, clear, and exact description.

This invention relates to animproveinentin shuttcrwvorkers in which a gear-wheel is fixed concentrically to the eye of the shutter-hinge leaf, and is engaged for swinging the shutter by a pinion on a turning spindle passing through the window-easing, and provided on its inner end with an operating-handle and a clutch device for locking or releasing the spindle.

The object of my improvement is to prevent the outside gearing from becoming clogged or injured by rain, ice, or snow, to provide for a ready dctaehability of parts for inspection or repairs, and to render the clutch mechanism on the operatinghandle safer to work and more durable.

The invention consists of certain novel combinations of parts and details of construction, hereinafter fully described, and distinctly pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an outside view of awindow having shutters provided with workers embodying my improvement. Fig. 2 is an enlarged inverted sectional plan view of a part of the same, taken on the line as as, Fig. 1. Fig. 3 isa sectional elevation of a part of the same,taken on the line g y, Fig. 2. Fig. lis alongitudinal sectional elevation of the spindlehandle and clutch device, taken on the line 2 2, Fig. 2.

The upper and lower hinges, A A, for each shutter B have their leaves 0 0 preferably curved laterally outward to bring the hingepins l),when said leaves are secured in the ordinary manner to the shutter B and the easing E, respectively medially in front of the casing.

The swinging shutter-leaf G of each lower hinge,A,is formed with a double eye,F,so as to embrace the single eye on the fixed casing-leaf O, and on the top of the double eye F is formed integrally and concentrically therewith an inverted crown-wheel, G, having downwardlyconed bevelteeth H, a closed roof projecting outward beyond the teeth H and a circular flange, I, depending from the edge of thcrooi', so as to prevent snow or rain from reaching the gear-teeth. A spindle, J, having squared outer and inner ends, J and J respectively, is passed through the window-casing ll) on each side in line with the hinge-pii1sl),and is mounted to turn in end bearings, K K, fixed to the casing. A bevel-pinion, L, having a square socket, is introduced between the flange I and the bevel-teeth H on theinverted crown-wheel G in position to receive in its square socket the squared outer end, J, of theturning spindle J, which end is fitted to the socket. The bevel-pinion L is thus held in place by the flange I on the one side and the crown-teeth H on the other, and can be easily removed on simply withdrawing thespindle.

A pin, M, is passed transversely through the spindle Jjust inside the casing E, and the inside spindle-bearing, K, is formed with an annular recess, K in its inner abut-ting face, to permit the pin to turn freely with. the spindle, whilepreventingthe spindle from being drawn inward.

The outer end of the bearing K is formed with a circular clutch-section, N, and the squared inner end, J", of the spindle, which projects from the bearing K, is inserted in a socket, O, considerably larger than the same, formed in a handle, 1?.

The outer end of the socket 0 has fixed thereto a contracted and square-holed collar, 0, to fit closely thesquared end J, but to play lengthwise thereomand on the squared end Jflconsiderably within the collar 0, is fixed a collar, Q, between which and the collar Oa coiled spring, R, is interposed. The outer end of the collar 0 has also fixed thereto or formed thereon clutch-teeth N, which are adapted to be held normally engaged with a fixed clutch-section, N, by the pressure of the spring 1%, and thus lock the handle, turning spindle, and hence shutter, in place. The square end J is formed also with a limited longitudinal slot, S, to receive apin, T, fixed to the outerhandle, P, and permit the same to be drawn outward just far enough to disengage the clutch-sections N N.

IOC

The spindle can then be turned by the handle to swing the shutter to any desired position, and when the handle is released the whole mechanism will be automatically locked, as before.

Having thus described my inventiomwhatl claim as new, and desire to secure by Letters Patent, is I In a shutter-worker, the operating-rod J, havinga reduced angular outer end, J provided with a recess, S, the bearing K, through which the round part of rodJ passes,pr0vided with an annular recess, K in its inner face, and having a clutch-section, N, on its outer face, the pin M, passed through rod J and [5 working in the recess K the handle P, having a socket, O, the collar 0, secured to the knob and having an angular opening, through which the part J of the rod J passes, and a clutch-section, N, on its outer face, the collar Q and spring R on part J within the socket, and the screw or pin T, passing through the wall of the socket into the recess S, substantially as set forth.
